Description
본 고안은 냉장고의 송풍장치에 관한 것으로, 보다 상세하게는 한 개의 릴레이(relay)를 이용하여 두 개의 송풍팬을 구동시키도록 한 냉장고의 송풍장치에 관한 것이다.The present invention relates to a blower of a refrigerator, and more particularly, to a blower of the refrigerator to drive two blower fans using a relay.
종래 냉장고의 송풍장치는 도시된 제1도와 같이, 냉장고의 냉동실 후측에 마련된 냉각기실의 후벽을 구성하는 내상 상부에 각각 냉동실 팬(22)과 냉장실 팬(24)이 회동가능하게 연결된 구동모터(20)가 설치되어 있다.The conventional blower of the refrigerator is a drive motor 20 in which a freezer compartment fan 22 and a refrigerating compartment fan 24 are rotatably connected to an upper portion of the inner wall constituting the rear wall of the cooler chamber provided at the rear side of the freezer compartment as shown in FIG. 1. ) Is installed.
즉, 구동모터(20)의 회전축(42)상에 두 개의 구동기어(44)가 설치 고정되어 있고, 이 구동기어(44)에 각각 그 선단에는 냉동실 팬(22)과 냉장실 팬(24)을 구비하고 그 중간에는 상기 냉동실 팬(22)의 회동을 단속하도록 제어부에 연결된 냉동실측 릴레이(60a)와 냉장실 팬(24)의 회동을 단속하도록 제어부에 연결된 냉장실측 릴레이(60b)가 각각 구비된 동력전달축(50')이 전달기어(54)에 의해 구동모터(20)의 회전축(42)상에 고정된 구동기어(33)에 치합되어 있다.That is, two drive gears 44 are mounted and fixed on the rotation shaft 42 of the drive motor 20, and the freezer compartment fan 22 and the refrigerating compartment fan 24 are respectively attached to the drive gears 44 at the ends thereof. And a refrigerating compartment side relay 60b connected to the control unit for intermittent rotation of the refrigerating compartment side fan 60a and the refrigerating compartment fan 24 to control the rotation of the freezer compartment fan 22 in the middle thereof. The transmission shaft 50 'is meshed with the drive gear 33 fixed on the rotation shaft 42 of the drive motor 20 by the transmission gear 54.
따라서, 해당 고내에 설치된 온도감지센서에서 감지된 온도에 따라 이를 판단하는 제어부의 제어신호에 의해 구동모터(20)의 회동력이 냉동실 팬(22)과 냉장실 팬(24)으로 전달되는 것을 단속하여 해당 고내로의 냉기공급을 제어하고 있었다.Therefore, the rotational force of the driving motor 20 is transmitted to the freezing compartment fan 22 and the refrigerating compartment fan 24 by the control signal of the controller that determines the temperature according to the temperature detected by the temperature sensor installed in the chamber. The supply of cold air into the furnace was controlled.
그런데, 이와 같은 종래의 냉장고 송풍장치는 두 개의 릴레이, 즉 냉동실측 릴레이(60a)와 냉장실측 릴레이(60b)를 각각 개별적으로 구비하고 있어 전체적인 생산원가가 증가하는 문제가 발생되었다.However, such a conventional refrigerator blower has two relays, namely, a freezer compartment relay 60a and a refrigerator compartment side relay 60b, respectively, so that the overall production cost increases.
또한, 상술한 두 개의 릴레이(60a)(60b)를 제어부에 전기적으로 연결하여 제어하기 위한 회로구성이 복잡하다는 문제도 내재되어 있었다.In addition, there is a problem in that a circuit configuration for controlling the two relays 60a and 60b described above electrically connected to the control unit is complicated.
본 고안은 상술한 바와 같은 제반 문제점을 감안하여 이를 해결하고자 안출된 것으로, 구동모터의 회전축 상에 고정된 두 개의 구동기어 사이의 회전축 상에 하나의 릴레이를 설치하여 두 개의 구동기어로 동시 전달되는 회동력을 단속하여 해당 고내로 냉기가 공급될 수 있도록 한 송풍장치의 제공을 그 기술적 과제로 하는 것이다.The present invention was devised to solve the above problems in consideration of the above-described problems, and one relay is installed on the rotation shaft between two drive gears fixed on the rotation shaft of the drive motor to be simultaneously transmitted to the two drive gears. The technical problem is to provide a blower that controls the rotational force so that cold air can be supplied into the refrigerator.

이하에서는, 본 고안에 따라 선호된 일 실시예를 첨부도면을 참조하여 보다 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment according to the present invention will be described in more detail.
제2도는 본 고안에 따라 하나의 릴레이(90)로 구동모터(20)의 회동력을 단속하여 냉장실 및 냉동실 팬 두 개의 회동을 제어할 수 있도록 설치된 송풍장치의 사시도이며, 제3도는 본 고안에 따른 릴레이(90)의 측단면도이다.2 is a perspective view of a blower installed to control the rotation of the refrigerating compartment and the freezing compartment fan by intermittent rotational force of the drive motor 20 with one relay 90 according to the present invention, FIG. Side cross-sectional view of the relay 90 according to the present invention.
본 고안의 제2도 내지 제3도와 같은 송풍장치는, 냉각기실에 설치된 증발기 상부 일측 내상에 한 개의 구동모터(20)가 고정설치되고, 상기 구동모터(20)의 회전축(42)이 연장되어 이 회전축(42) 상에 두 개의 구동기어(44a)(44b)가 상호간에 적당한 간격으로 떨어져 설치 고정되어 있다.In the blower of FIGS. 2 to 3 of the present invention, one drive motor 20 is fixedly installed on one side of an upper side of an evaporator installed in a cooler chamber, and a rotation shaft 42 of the drive motor 20 is extended. On the rotary shaft 42, two drive gears 44a and 44b are mounted and fixed apart from each other at appropriate intervals.
그리고, 상기 구동기어(44a)(44b) 사이의 회전축(42) 상에는 제어부에 전기적으로 연결된 릴레이(90)가 설치되어 있다.The relay 90 is electrically connected to the controller on the rotation shaft 42 between the drive gears 44a and 44b.
또한, 그 선단에는 송풍팬(22)(24)이 고정되고, 그 후단에는 전달기어(54)가 고정된 동력전달축(50)의 상기 전달기어(54)가 구동기어(44a)(44b)에 치합되어 있다.In addition, the transmission gears 54 of the power transmission shaft 50 having the blower fans 22 and 24 fixed to the front end and the transmission gear 54 fixed to the rear end are driven gears 44a and 44b. Is in conflict with
또한, 상기 릴레이(60)에 삽입되어 있는 릴레이(60) 내부의 회전축(42)은 분리되어 있고, 그 분리된 단부는 상호간에 결합가능토록 요철부(72a)(72b)를 이루고 있다.In addition, the rotation shaft 42 inside the relay 60 inserted into the relay 60 is separated, and the separated ends form concave-convex portions 72a and 72b so as to be mutually engageable.
뿐만 아니라, 상기 회전축(42)의 분리된 일단중 요부(72a)의 일부에 그 외주를 따라 돌기(69)가 형성되어 있고, 이 돌기(69)에는 원형철심(68)이 고정되어 있으며, 철심(68)과 소정간격을 두고 상부에는 원형코일(64)이 설치되어 있는 바, 상기 원형코일(64)의 동심원 상에 원형철심(68)이 설치되어 있으며, 이 원형코일(64)은 제어부에 전기적으로 연결되어 있다.In addition, a protrusion 69 is formed along a periphery of a part of the recessed portion 72a of the separated end of the rotating shaft 42, and a circular iron core 68 is fixed to the protrusion 69. A circular coil 64 is provided at an upper portion with a predetermined interval of 68, and a circular iron core 68 is installed on the concentric circle of the circular coil 64, and the circular coil 64 is connected to the control unit. It is electrically connected.
또한, 릴레이(60)의 선후단에는 베어링(56)이 설치되어 있어, 여기로 상기 철부(72b)가 형성된 회전축(42)의 일단이 삽입되며 상기 회전축(42)의 요부(72a)가 형성된 타단이 삽입되는 베어링(56)의 후부와 철심(68) 사이에는 원형철심(68)을 항상 탄압하여 회전축(42)의 요부(72a)가 철부(72b)와 맞물려 있도록 하여주는 스프링(62)이 개재되어 있다.In addition, a bearing 56 is provided at the front and rear ends of the relay 60, and one end of the rotating shaft 42 having the convex portion 72b is inserted therein, and the other end having the recessed portion 72a of the rotating shaft 42 formed therein. Between the rear part of the bearing 56 to be inserted and the iron core 68 is interposed a spring 62 which always suppresses the circular iron core 68 so that the recessed portion 72a of the rotating shaft 42 is engaged with the iron portion 72b. It is.
이러한 구성으로 이루어진 본 고안의 송풍장치는, 냉동실 및 냉장실 각각에 설치된 온도센서(미도시)에서 감지된 고내 온도의 변화에 따라 제어부가 판단하여 해당 송풍팬(22)(24)의 구동을 제어하도록 작용하는 바, 이는 제어부가 판단된 제어신호에 의해 구동모터(20)와 릴레이(60)에 전원인가를 단속함으로서 이루어진다.The blower according to the present invention having such a configuration is configured to control the driving of the blower fan 22 or 24 based on a change in the internal temperature detected by a temperature sensor (not shown) installed in each of the freezer compartment and the refrigerator compartment. This is done by controlling the power supply to the driving motor 20 and the relay 60 in response to the determined control signal.
즉, 일단 냉장고가 냉각모드로 전환되어 압축기(미도시)가 구동되면 냉각기실에 설치된 구동모터(20)는 압축기와 연동되어 구동모터(20)의 회전축(42)을 회동시키게 된다.That is, once the refrigerator is switched to the cooling mode and the compressor (not shown) is driven, the drive motor 20 installed in the cooler chamber rotates the rotary shaft 42 of the drive motor 20 in association with the compressor.
따라서, 상기 회전축(42) 상에 고정된 냉동실용 구동기어(44a)도 동시에 회동되며, 이 구동기어(44a)에 치합된 전달기어(54)가 회동되어 동력전달축(50)도 동시에 회동됨으로서 냉동실로의 냉기공급은 압축기의 구동과 항상 동시 병행된다. 또한, 이러한 압축기의 구동은 오로지 냉동실에 설치된 온도센서에만 의존하게 된다.Therefore, the freezer compartment drive gear 44a fixed on the rotating shaft 42 is also rotated at the same time, and the transmission gear 54 engaged with the drive gear 44a is rotated so that the power transmission shaft 50 is also rotated at the same time. The cold air supply to the freezer is always concurrent with the drive of the compressor. In addition, the operation of such a compressor only depends on the temperature sensor installed in the freezer compartment.
반면, 냉장실의 경우에는 고내에 설치된 온도센서의 감지신호에 따라 제어부에서는 릴레이(90) 내부에 설치된 원형코일(64)에 전기인가 여부를 결정하게 되고, 만약 전기가 인가되면 원형코일(64)에 인가된 전기는 코일(64) 내부에 자기장을 형성하게 되어 철심(68)이 스프링(62)의 인장력을 극복하고 밀려나게 됨으로서, 회전축(42)의 요철부(72a)(72b)가 분리되어 구동모터(20)의 회동력이 냉장실용 구동기어(44b)에 전달되지 않게되어 송풍팬(24)이 정지하게 된다.On the other hand, in the case of the refrigerating chamber, the control unit determines whether or not electricity is supplied to the circular coil 64 installed inside the relay 90 according to the detection signal of the temperature sensor installed in the refrigerator. The applied electricity forms a magnetic field inside the coil 64 so that the iron core 68 overcomes the tensile force of the spring 62 and is pushed out, so that the uneven parts 72a and 72b of the rotating shaft 42 are separated and driven. Since the rotational force of the motor 20 is not transmitted to the drive gear 44b for the refrigerating chamber, the blower fan 24 is stopped.
아울러, 냉장실 고내 온도가 상승되어 냉기공급이 필요하다고 판단되면, 제어부의 제어신호에 따라 원형코일(64)에 전기가 인가되지 않으므로 스프링(62)의 인장력이 철심(68)을 밀게되어 회전축(42)의 요철부(72a)(72b)가 상호 결합 연결되므로서 냉장실용 구동기어(44b)가 회동되면서 송풍팬(24)이 회동되어 냉기공급이 이루어지게 된다.In addition, when it is determined that the temperature in the refrigerator compartment is raised to supply the cold air, since the electric power is not applied to the circular coil 64 according to the control signal of the controller, the tensile force of the spring 62 pushes the iron core 68 to rotate the rotary shaft 42. As the concave-convex portions 72a and 72b are connected to each other and the driving gear 44b for the refrigerating chamber is rotated, the blower fan 24 is rotated to supply cold air.
상술한 바와 같이, 냉동실로의 냉기공급은 냉동실에 설치된 온도센서에 따라 구동하는 콤프레서, 구동모터에 의해 이들의 구동과 동시에 냉기가 공급되며, 또한 이들의 구동정지시 이들과 함께 냉기공급이 중단된다.As described above, the cold air is supplied to the freezing chamber by the compressor and the driving motor driven by the temperature sensor installed in the freezing chamber, and the cold air is supplied at the same time when the driving is stopped. .
한편, 냉장실로의 냉기공급은 상기 냉동실로의 냉기 공급이 진행중에, 즉 구동모터가 구동되고 있을 때에만 고내에 설치된 온도센서의 감지에 따라 냉기의 공급이 단속되는 것이다.On the other hand, the supply of cold air to the refrigerating chamber is that the supply of cold air is interrupted according to the detection of the temperature sensor installed in the refrigerator only during the supply of the cold air to the freezing chamber, that is, when the driving motor is being driven.
이상에서 살펴 본 바와 같이, 본 고안에 따른 냉장고의 송풍장치는, 한 개의 릴레이로 두 개의 팬 회동을 단속시켜 냉동실 및 냉장실로의 냉기공급을 하도록 되어 있으므로 기존과 같이 두 개의 릴레이를 설치할 때 보다 훨씬 경제적이며, 복잡한 전기회로를 구성하지 않아도 되기 때문에 제어부의 에러발생 빈도를 감소시킬 수 있으므로 보다 완성도 높은 냉장고를 제공할 수 있는 특장점이 있다.As described above, the blower of the refrigerator according to the present invention is to supply the cold air to the freezer compartment and the refrigerating compartment by intermitting two fan rotations with one relay, which is much more than when installing two relays as before. Since it is economical and does not need to configure a complicated electric circuit, it is possible to reduce the frequency of error occurrence of the control unit, and thus there is a feature of providing a more complete refrigerator.
